To all whom it may concern.

Be it known that 1, ROBERT Himsrr, a subect of the King of Hungary, and a resident of Tuckahoe, in the county of Vestchester and State of New York, have invented certain new and useful Improvements in Attachments for Internal-Combustion Engines, of which the following is a specification.

The present invention relates to an attachment for internal combustion engines, more particularly to a primer, that is to say a device designed to introduce a fluid into the working cylinders of the engine to form a combustible mixture which is ignited to start the engine.

One of the objects of the invention is to provide a primer that is adapted to be inserted into the inlet manifold or fuel supply pipe of an internal combustion engine, serving at the same time to introduce into the said manifold or pipe an additional quantity of air to produce a uniform mixture.

Another object of the invention is to construct a primer of the type mentioned which can be conveniently attached to internal combustion engines of all types.

A further object of the invention is to combine the primer with means which permits of an introduction of hot water into the cylinder or cylinders of the engine, wherein it is converted into steam for the purpose of removing carbon deposits from the said cylinders.

A. still further object of the invention is to combine the priming device with a pipeline leading to a fire extinguishing mechanism to allow of an introduction of fire extinguishing fluid or other material into the carbureter in case the hydrocarbon therein should become ignited.

WVith these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departin from the spirit or sacrificing any of the advantages of the invention.

Two of the many possible embodiments of the invention are illustrated in the accompanying drawings, in which:

Figure 1 is a central vertical section taken through the primer constructed in accord ance with the present invention; Fig. 2 is a section taken on line 22 of Fig. 1; Fig. 3 is a top plan view thereof; Fig. 4 is a section taken on line 4-4 of Fig. 2; Fig. 5 is a side elevation of the top portion of the cylinders of a two cylinder internal combustion engine with its intake manifold and carburetor,

showing the primer mounted thereon; Fig.-

6 is a top plan view of the device shown in Fig. 5; Fig. 7 is a top plan view of a modified device; F ig. 8 is a section taken on line 88 of Fig. 7 and Fig. 9 is a side elevation of a portion of a two cylinder internal combustion engine showing the attachment illustrated in Figs. 7 and 8 applied thereto.

Referring now more particularly to Figs. 1 to 6, inclusive, the numeral 10 indicates the cylinders of an internal combustion engine, to the inlet ports of which leads an intake manifold or supply pipe 11, communicating with a carbureter 12 of any suitable construction. The end of the pipe 11. adjacent to the carbureter, is provided with a flange 13, in registering position with the flange 14 of the carburetor outlet, and between these two flanges 'is held by screw' bolts 15, or otherwise, a bracket 16, the latter supporting a receptacle 17, that is adapted to contain the priming fluid. That portion of the bracket 16 which is clamped between the flanges 13 and 14 corresponds to the configuration of said flanges, and is provided with a round opening 18, the diameter of which corresponds substantially to the inner diameter of the supply pipe 11, so as not to obstruct the passage of the combustible mixture from the carburetor to the engine cylinders. Around the opening 18 is formed an annular closed passage 19, diametrically opposite portions of which are connected by a tube 20, that extends across the opening 18 and is provided with apertures 21, the latter facing the manifold 11. The passage 19 communicates with the interior of the receptacle 17 through a channel 22, that is formed the bottom extend upwardly arc-shaped guides 24, surrounding the mouth of the tubular valve casin stantial distance above the said cover.

channel 22 and engagin the lower enlarged end 25 of a tube 26, which is disposedwithin the receptacle 17 and projects through an opening 27 in the cover 28. thereof a sulb o the upper end of the tube 26is attached a 29, provided with a section-30 that exten s at right angles to the .longitudinal axis of the tube 26. The secvalve has an aperture- 33, that is adapted to register with the passagein that portlon of the valve casing that communicates with the tube 26. The valve is provided outside of the valve casing with a nipple 34, to which is adapted to be attached a, preferably, flexible tube 35 (Fig. 6).

To the valve casing is secured a sprmg stop 36, provided with a pointed end 37,

adapted to be seated in anyone of a row of notches 38, that are formed in the arcshaped portion 39 of a lever 40, the latter being secured to the valve 32 outside of the valve casing. Upon the valve casing 29 is furthermore formed an arm 41,- against which bears one end of a bellcrank lever 42, which is fulcrumed at 43' to a standard 44 upon the cover 28 of the receptacle. One

end of the bellcrank lever is connected, preferably, by a flexible connection 45 with an actuating lever, disposed within the reach "of the operator. In the top 28 of the receptacle are formed air-ports 46, normally closed by a valve 47 which is kept upon its seat by a spring 48. This spring is normally slightly compressed, one of its ends being attached to the valve casing 29 and its other end to the valve 47, so that, when the tubular member 26 is raised, the valve 47 will also be raised after the spring 48 has been expanded to its full length. A spring 49 is coiled upon the tube 26, said spring bearing against the cover 28 of the receptacle 17 and against the enlargement 25 of the tube 26. Upon the bracket 16 is formed a nipple 50 in communication with the channel 22 in the said bracket. To this nipple leads a pipe 51: into which is inserted a cock 52. Into the pipe 51 adapted to be injected a fire extinguishing 'liquid or other material, as will hereinafter appear.

The operation of this device is as follows:

Let us suppose that the device herein described is attached to an internal combus-,

v45 is attached, is disposed in front of the seat of the chauffeur. The valve 32 is set to its open or partially open position to permit of an inflow of air'into the passage 19,

according to the requirements. For the purpose of setting this valve, the spring stop 36 is first disengaged from the arc-shaped portion of the lever 40 and the latter turned until the desired opening is obtained, after which the spring stop 1s engaged with one of the notches 38 in said lever, thereby holding the valve in fixed position. If it is intended to start the engine, the bellcrank lever 42 is shifted by taking hold of the lever to which the flexible connection 45 is connected.

drawn partly through the carbureter and also through the tube 26 as soon as the latter is caused to occupy its normal position (Fig. 1) upon releasing the flexible connection- 45. The airflows through the apertures 21 in the tube 20 in streams, entrains and atomizes and sprays the priming fluid in the intake manifold, thus forming a combustible mixture. It is to be observed that, as the tube 26 is lifted, the air-ports 46 are uncovered by the valve 47 and admit air on top of the priming fluid into the receptacle 17, with the result that atmospheric pressure will always prevail-in the said receptacle, thereby enabling the priming fluid to flow into the channel 22 when the device is actuated in the manner above described. Dur ing the normal operation of the engine, additional air is admitted into the intake manifold through the tube 26, which air serves to produce a more uniform mixture. In case by back-fire or otherwise the liquid hydrocarbon is ignited in the carburetor, the cock 52 is set to its opening position and a charge of fire extinguishing fluid or other material forced into the tube 51, wherein it willfiow through the'nipple 50, channel 22, passage 19 and apertures 21 into the carbureter, extinguishing the fire therein. If it is intended to steam the cylinders of the engine for the purpose of removing the carbon deposits therein, a, preferably, flexible tube 35 is connected with the nipple 34 of the valve 32, the other end of said tube being inserted into the radiator 55 of the automobile, or' to some other water source if the engine is not mounted upon an automobile. The valve 32 is then set to its almost closing position so as to admit a small supply of water only, as otherwise the engine would .be stalled. As the engine is now being run,

water will be sucked through the tube 26 lOt into the intake manifold, wherein it is sprayed and caused to,-flow into the cylinders. In the cylinders it is converted into steam, the latter having a tendency to loosen the carbon deposits in the cylinders. These deposits are carried away from the cylinders by the exhaust gases. v

A modification of the invention is illustrated in Figs. 7 to 9, inclusive. In this construction the device comprises a base plate 60, that is inserted between the flanges 61 and 62 of the inlet manifold 63 and carbureter 64, respectively. This base plate is provided with a circular opening 65, in alinement with the outlet ofthe. carbureter and the inlet to the intake manifold. With the opening 65 communicates a tube 66, the inner end of which is flattened, as shown at 67, or in other words shaped so as to be suitable to extend through the base plate, which is made in, the form of a comparatively thin flange. The tube terminates in a nipple 68 and has inserted thereinto a cook 69. A strainer 70 may be mounted upon the base plate for the well known pur ose. p In operation, if the cook 69 is set to its open or partially open position, additional air will flow into the intake manifold for the purpose above described. For steaming the cylinders of the engine or for fire extinguishing purposes, a flexible tube 35 is connected to the nipple 68 and its other end inserted into the radiator 55 or connected to a fire extinguisher, in which cases the device operates in the manner described in connection with Figs. 1 to 6, inclusive.
